We look at the division of 436137 by 41 
The aim is to understand the frequency of 41 in 436137.

Going ahead to step 1:
The number 41 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 41

Going ahead to step 2:
When dividing 43 by 41, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 41 from 43 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 41

On to step 3:
The number 41 fits into 26 0 times, leaving a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 26 after subtracting 0 from 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 41

Moving on to step 4:
When dividing 261 by 41, we get 6 with a remainder of 15.
The next digit of our result is 6. 
Result so far: 106.0
Subtracting 246 from 261 leaves us with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 41

Advancing to step 5:
41 can be fit into 153 3 times, resulting in a remainder of 30.
The next digit of our result is 3. 
Result so far: 1063.0
Deduct 123 from 153 and we're left with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 41

On to step 6:
41 goes into 307 7 times with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 10637.0
Subtracting 287 from 307 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
41 can be fit into 200 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 10637.4
Subtract 164 from 200 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
360 divided by 41 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 10637.48
If we subtract 328 from 360, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
320 divided by 41 is 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 10637.487
Subtracting 287 from 320 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 10:
When dividing 330 by 41, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 10637.4878
Subtract 328 from 330 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
The number 41 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 10637.4878
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
41 goes into 200 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 10637.487804
The remainder is 36 after subtracting 164 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
41 goes into 360 8 times with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 10637.4878048
Deduct 328 from 360 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
320 divided by 41 is 7 with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 10637.48780487
Subtract 287 from 320 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

In conclusion, the division gives 10637.48780487 with a balance of 3.3e-08.
